How to Fix a Webflow Layout That Breaks on Tablet and Mobile

Why it matters

Google uses the mobile version of a site's content for indexing and ranking. Google recommends responsive design, which serves the same HTML on the same URL and changes how content looks by screen size.

So a layout that breaks on mobile is not a small problem. It affects your visitors, and it affects the version of the page Google reads.

How to check it

1. Switch breakpoints in the Designer. Webflow's defaults are Tablet (991px and below), Mobile landscape (767px and below) and Mobile portrait (479px and below).
2. Click the element that looks wrong. In the Style panel, blue means the style is set on this breakpoint. Orange means it is inherited from another breakpoint.
3. Look for fixed pixel widths. A pixel width wider than the screen is a common reason a layout overflows.
4. Look for sideways scrolling in preview.
5. See what Google sees. In Search Console, inspect the URL and click Test live URL. Then click View tested page and open the Screenshot tab. Google says the details, including the screenshot, come from the mobile version of the page.

How to fix it in Webflow

1. Start at the largest breakpoint that breaks. Styles flow down from Desktop to Tablet to Mobile. Styles set on a smaller breakpoint override styles from the one above. A fix at Tablet carries down unless something overrides it.
2. Reset stray overrides. Click the blue or orange indicator next to a property and choose Reset. You can also hold Option (Mac) or Alt (Windows) and click. Fewer overrides means fewer surprises.
3. Swap fixed widths for flexible ones. Webflow supports px, %, em, rem, vw, vh, vmin, vmax, fr and ch. Use %, fr or auto where you can.
4. Plan for Safari. Webflow warns that Safari, including on iOS, may render layouts differently when elements use auto or % and no parent has a fixed pixel size. If an element collapses there, give a parent a pixel size.
5. Let flex rows wrap. Flexbox can move child elements to the next line when they reach the edge of the parent. Turn wrapping on instead of squeezing items.
6. Set grids and Quick Stack per breakpoint. On tablet and mobile, a Quick Stack's row value becomes Auto and fills based on the column value. To change a cell's span, use Style panel, Cell size. To reorder cells, use Cell size, then order.
7. Stop sideways scrolling. Select the parent wrapper. Go to Style panel, Size, and set Overflow to hidden. Webflow says this prevents unwanted horizontal scrolling and extra whitespace. Do not set it on the body. That can clip the page and stop people from scrolling. Use a wrapper div instead.
8. Keep the same content. Do not hide key text or images on mobile to make the layout fit. Google says your mobile site should contain the same content as your desktop site.
9. Publish and test. Check every breakpoint again. Check Safari too.

Checklist

• You know which breakpoint breaks first.
• Blue and orange style indicators are reviewed.
• Stray overrides are reset.
• Fixed pixel widths are replaced where possible.
• Flex rows wrap.
• Grid and Quick Stack are set for tablet and mobile.
• Overflow hidden is on a wrapper, not the body.
• Mobile has the same content as desktop.
• The page is tested in Safari.
• The Search Console screenshot looks right.

FAQ

Why does my layout look fine in the Designer but wrong on iPhone?

Safari can render layouts differently, especially with auto or % sizes when no parent has a pixel size. Give a parent a fixed pixel size and test again.

Can I hide content on mobile to fix the layout?

It is risky. Google says mobile should have the same content as desktop. Rearrange or resize it instead.

Why did my sticky element stop working after I added overflow hidden?

Webflow says position sticky does not work if any parent has Overflow set to hidden. Remove it from every parent of the sticky element.
